Dimedone is an interesting and versatile motif in most organic transformations. Its white to light yellow crystals have been utilized as substrate in wide range of organic reactions including multi-component transformations. The notability of dimedone is due to the acidic property of its methyle...
With purpose to prepare waterborne polyurethane with improved performance, bis(methyoxyl hydroxyl)-functionalized polysiloxanes with different dimethylsiloxane segment length were prepared. The preparation includes three steps, the first is synthesis of 1,3-bis(glycidoxypropyl)tetramethyldisilox...
Cypermethrin (Ripcord) and demeton-S-methyl (Duratox) were each applied to large fields of winter wheat by fixed-wing aircraft. The numbers of soil surface- and foliar-dwelling arthropods were estimated at intervals before and after treatment in both the treated and an untreated control field, u...
The organophosphorus insecticide, demeton-S-methyl (DSM), is considered as a good surrogate of the highly toxic nerve agent VX for skin absorption studies due to similar physico-chemical properties and in vitro percutaneous penetration profile. But, when skin distribution was estimated by measur...
Butyrylcholinesterase-encapsulating bioadhesive liposomes are investigated as prophylactic scavengers of organophosphates for local administration to skin, eyes, airways, and lungs—gates through which organophosphates penetrate living systems. The systems were optimized with respect to: encapsu...
Publisher SummaryThis chapter provides the basic synthesis paths routes for the manufacture of demeton-s-methyl, with a listing of the main raw materials and intermediates used in the synthesis of demeton-s-methyl. Demeton-S-Methyl is commercially known as Metasystox and it belongs to the phosph...
Publisher SummaryThis chapter provides the basic synthesis paths routes for the manufacture of demeton-s-methyl sulphon, with a listing of the main raw materials and intermediates used in the synthesis of demeton-s-methyl sulphon. Demeton-S-Methyl Sulphon is commercially known as Metaisosystox s...
Diffusion, rheology, and small angle neutron scattering (SANS) data for organic phase 30 v/v % tributyl phosphate (TBP) samples containing varying amounts of water, nitric acid, and uranium or zirconium nitrate were interpreted from a colloidal perspective to give information on the types of str...
The solubilities of sulfuryl fluoride (SO2F2) in propylene carbonate (PC), tributyl phosphate (TBP) and N-methylpyrrolidone (NMP) was measured by isochoric saturation method at the pressure of up to 600 kPa and temperatures ranging from (293.15 to 313.15) K. Results showed that SO2F2 solubility ...
Red oil incidents reported worldwide are attributed to the reactive thermal reactions between Tributyl phosphate (TBP) and nitric acid. The vigor of thermal behavior may be influenced by various factors including irradiation, presence of metal nitrates etc. This work is focused to study the infl...
Tributyl phosphate (TBP) belongs to the group of trialkyl substituted organophosphate esters. Its chemical reactivity depends on the stability of various chemical bonds. TBP was used as a model compound for the development of a concept using stable isotope fractionation associated with bond clea...
The process of recovery by direct extraction of metal bromides from calcium chloride brines using mixtures of molecular iodine with tributyl phosphate has been studied. It was found that iodine significantly increases the recovery of the bromides of alkali and alkaline earth metals due to the fo...
Tributyl phosphate (TBP) is recognised as a global environmental contaminant because of its wide use in floatation reagents, nuclear fuel reprocessing and plasticisers. This contaminant is hardly degraded by hydrolysis in the environment due to its special physicochemical properties. In this stu...
In this work, surface tension was determined for binary mixtures of imidazolium based ionic liquids (ILs) and tributyl phosphate (TBP) over the whole composition range at temperatures from (293.15 to 323.15) K and atmospheric pressure. The ILs, 1-butyl-3-methylimidazolium tetrafluoroborate ([Bmi...
Removal of SO2 and NO emissions from coal-fired power plants have always been the focus in coal's utilization industries for which traditional wet desulfurization system hold the potential to achieve simultaneous removal of SO2/NOx. In this work, a novel liquid catalyst (tributyl phosphate,...
The flame retardant tris(2,3-dibromopropyl)phosphate(Tris-BP) was studied for nephrotoxicity and covalent protein binding in vivo to rat, mouse, hamster and guinea pig protein. In addition, Tris-BP mutagenicity to S. typhimurium TA 100 and covalent protein binding in vitro was determined with he...
A study was undertaken to determine the teratogenic potential of tris-(2,3-dibromopropyl) phosphate (TRIS), the flame retardant formerly used in clothing. TRIS, in undiluted propylene glycol, was orally intubated into pregnant Sprague-Dawley rats on days 6–15 of gestation at a level of 0, 5, 25...
Tris(2,3-dibromopropyl) isocyanurate (TBC) is a novel brominated flame retardant (BFR) that is widely used to substitute the prohibited BFRs throughout the world. With the development of research, the potential environmental and ecological harms of TBC have been revealed. For sensitive and selec...
The nephrocarcinogen tris(2,3-dibromopropyl)phosphate (Tris-BP) caused extensive acute renal tubular necrosis at doses of 175 mg/kg, ip, and higher in rats. Pretreatment with cobalt chloride lead to a moderate reduction in Tris-BP nephrotoxicity, whereas pretreatments with the cytochrome P-450 i...
The potent mutagen 2-bromoacrolein is formed from the carcinogenic flame retardant tris(2,3-dibromopropyl)phosphate (Tris-BP) on incubation with hepatic microsomes. Substitution of deuterium for hydrogen at the terminal carbon atoms (C-3) of Tris-BP significantly decreased both the mutagenic res...
